Wasn't trying to start an argument. Glad your studding pattern is working for you with your current track. You did state that you had a track failure once due to an outer stud related failure that took out a heat exchanger didn't you?
I don't like to have to be concerned about the outer studs when trail conditions get a little worse for wear, like they do frequently in Michigan. Having to worry about my track when I'm sledding with friends and the trails are whooped can sure put a damper on the trip while they are way up front having fun. If the corners were always groomed and snow covered, that may be a different story. I'm just relating what happened to me when I used to stud the outer belt. I want the stud to bend or break BEFORE the track is damaged, and that's been my experience since I started studding just in the center. I'd much rather replace a couple studs every season than a track. I'm putting a track in now and it's not the most fun job. 1.325" studs or longer like the original post was suggesting are awfully long to be out on the edges imo but yes, there are folks that do it. I have a Ripsaws on a couple sleds now and they are not particularly beefy tracks.
